Question

Write an inequality for the given temperature: The temperature is at almost 20 degrees outside.

a. T ≥ 20
b. T < 20
c. T ≤ 20
d. T > 20

Answer 1

The correct inequality for the temperature being almost 20 degrees outside is T < 20, meaning the temperature is less than 20 degrees.

Step-by-step explanation:

When interpreting the phrase 'almost 20 degrees outside,' it suggests that the temperature is not quite 20 degrees, but it is close. Therefore, the correct inequality would be T < 20, which indicates that the temperature is less than 20 degrees. This aligns with option 'b' from the choices provided. It's important to note that no conversion to kelvins is necessary for this particular inequality; the context is purely mathematical rather than scientific or involving absolute temperatures where kelvins would be relevant.
